Authorities in the Russian-controlled eastern Ukrainian town of Horlivka have installed jamming devices on some of the local buses to protect them from drone strikes, officials told Reuters. At least one bus driving around the town, located near the Russian-held city of Donetsk, was attacked by a Ukrainian drone this month, Russian-affiliated authorities say, and three people were wounded in the incident. Jammers work by disrupting a drone’s communications with its operator, making it less dangerous, although crashing drones have also caused damage in a number of incidents in the Russia-Ukraine war.
